Removing string inside brackets

Question

Good day!

I would like some help in removing strings inside the square brackets and including the square brackets.

The string looks like this:

$str

Answer 1

The below code will change
to newline characters:

$str = "Lorem ipsum dolor
[ Context are found on www.example.com ] 
some text here";
$str = preg_replace( "/\[[^\]]*\]/m", "", $str);
echo $str;

Output:

Lorem ipsum dolor

some text here
